Problems solved by technology

[0002] At present, there are various types of pipe benders commonly used at home and abroad, including pure mechanical type, hydraulic type, pneumatic type, and intermediate frequency induction heating type. They usually occupy a large area, have complex mechanisms, and are bulky.
Bend pipe defects mainly include severe flattening of the arc (oval shape), excessive thinning of the outer tube wall of the arc, bending cracks on the outer side of the arc, wrinkling on the inner side of the arc (wavy wrinkles) and only one-way bending and other defects
Traditional manual and imitation pipe bending is labor-intensive and the production efficiency is not high

Abstract

A numerical control servo automatic bending machine comprises a machine body, a core pulling device, a feeding clamping device, an auxiliary pushing mechanism, an auxiliary pushing oil cylinder, a clamping oil cylinder, a driving arm, a rotary servo motor, a bending die and a feeding device. The bending die is divided into two bodies, an upper die body can move vertically to loosen and clamp workpieces. The numerical control servo automatic bending machine is characterized in that the rotary servo motor drives the die and drives feeding to be conducted, and the length and width precision and the angle precision of a frame are guaranteed; and the core pulling device acts to guarantee the precision of bent arc sections. According to the numerical control servo automatic bending machine, the servo motor is used for driving; loosening, clamping and feeding are achieved automatically; PLC control guarantees the rotating precision and the feeding precision; one-time feeding at four bent corners is conducted sequentially, the precision is high and stable, the efficiency is greatly improved and is 4-5 times that of a traditional machining mode.

Description

technical field [0001] The invention relates to a numerical control servo automatic bending machine used in the production of rail vehicle doors (windows) and screen doors. Background technique [0002] At present, there are various types of pipe benders commonly used at home and abroad, including pure mechanical type, hydraulic type, pneumatic type, and intermediate frequency induction heating type. They usually occupy a large area, have complex mechanisms, and are bulky. Bend pipe defects mainly include severe flattening of the arc (oval shape), excessive thinning of the outer tube wall of the arc, bending cracks on the outer side of the arc, wrinkling on the inner side of the arc (wavy wrinkles) and only one-way bending and other defects. The traditional manual and imitation pipe bending is labor-intensive and the production efficiency is not high. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies, the object of the present inven...
